Issue 1: I've noticed that sometimes when I turn the car off, I can close the sunroof.

Q1. Is there suppose to to be some reserve power?

Issue 2: MY LED eyes have a very short life span. I examined one and there was a burn mark.

Q2. Does that mean a bad ground? This suggests that some serious is "surging" going on.

Issue 3: On Unlock, fogs and headlight don't always come on at night.

Car: 2009 C350 with just over 81,000 miles.

The dealership has replaced the following.

A. Faulty steering column lock.
B. Rear tail light harness due to recall.
C. iPod cable broke and was replaced.

Any insight is appreciated.
